The first attempt to turn Green New Deal proposals into legislation would overhaul 1 million public housing units to make them carbon neutral.

Rep. Alexandra Ocasio-Cortez, D-New York, and Democratic presidential candidate Sen. Bernie Sanders of Vermont introduced the Green New Deal for Public Housing Act that would use seven grant programs to upgrade public housing to include organic grocery stores, onsite child care and community gardens. Cost estimates vary depending on an organization’s political affiliation, falling between $119 billion and $172 billion over the next decade, according to left-leaning Data for Progress and a more than $1.6 trillion estimate from right-leaning American Action Forum…

And then there’s the issue of how solar panels or wind turbines are manufactured or installed, which Steve Milloy, the founder of Junk Science, said is impossible without the fossil fuels that Green New Deal advocates and others want to eliminate. Additionally, the costs associated with decarbonization are “astronomical.”

“It’s all kinds of ridiculous,” Milloy said, pointing to California’s mandate to have 5 million electric cars on the state’s roads by 2030. “You’d have to double the amount of rare earth mineral mining in the world just to do that.”
